About partition type ID

Most computer users may be familiar with partitions and partition types. Actually, there are five partition types: primary, extensible firmware interface (EFI), extended, logical, and Microsoft Reserved (MSR). How about partition type ID?

Partition type ID is a byte value intended to specify the file system a partition contains and/or to flag the special access method used to access the partition.

For MBR disks, the value for the type field is in hexadecimal form. Following are the frequently-used type IDs for MBR-based partitions:

● 0x01 FAT12
● 0x04 FAT16, less than 32 MB
● 0x06 FAT16, greater than 32 MB
● 0x07 NTFS
● 0x0B FAT32, used by DOS & Win95
● 0x0C FAT32 using LBA mode to access to FAT32 partition
● 0x0E FAT16 using LBA mode to access to FAT16 partition

For GPT disks, the value for the type field is a long string. Recognized GUIDs include:

◆ EFI system partition: c12a7328-f81f-11d2-ba4b-00a0c93ec93b
◆ Basic data partition: ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
